Abstract

The invention discloses a disc micro-cavity laser device with an output waveguide. The disc micro-cavity laser device comprises a substrate and an upper layer structure, wherein the substrate is rectangular; the upper layer structure is manufactured on the substrate; the upper layer structure comprises a resonant cavity and a strip output waveguide, wherein the resonant cavity is circular; and one end of the strip output waveguide is connected with the lateral surface of the resonant cavity, and the resonant cavity and the strip output waveguide form a table tennis bat-like structure.

Description

technical field [0001] The present invention relates to the field of semiconductor lasers, and in particular to laser light sources. More specifically, the present invention relates to a disk microcavity laser with a strip-shaped output waveguide, wherein the strip-shaped output waveguide can enable the microcavity laser to achieve directional output and single-mode operation. Background technique [0002] With the advancement and innovation of modern information technology, optoelectronic devices are gradually developing towards high-density integration, high efficiency, low power consumption and miniaturization. At present, most traditional semiconductor lasers are difficult to achieve this goal. The optical microcavity achieves strong confinement of the light field through total reflection, and a whispering gallery (Wispering-Gallery, WG) mode with a very high quality factor is generated in the cavity, which has a small mode volume, low power consumption, ultra-fast respon...
